Just pointed that the article you're using as a trustworthy source isn't really consistent. I chose examples that are all around, that was the point. In one there's a (ignored) confession, another has the girls basically married, but without a word being confirmed, and so on.
About the tagging (in Dynasty), sure, if you want to go technical, you probably may say that many of the works don't qualify as yuri genre (for which it's possible many works that even have confessions wouldn't qualify), but Yuri
is used here to indicate the content of a given work, specifically, that there's a female that has romantic and/or sexual feelings for another female. It's also worth mentioning that yuri crush
, as a dynasty tag, is not synonymous with "one-sided love", which still falls into yuri
.
